invoke($myClass, 'Hello', 'World'); ?>
invokeArgs(array('Hello', 'World')); ?>This example defines a function `foo` that takes two parameters. Then, it creates a `ReflectionFunction` object for the `foo` function. Finally, it uses the `invokeArgs` method of the `ReflectionFunction` object to call `foo` with the parameters 'Hello' and 'World'. Running this code will output "param1: Hello, param2: World". The package library used for `ReflectionMethod` and `ReflectionFunction` classes is part of the core PHP language.
